WIRE-CONNECTOR.

To all whom it may concern Be it known that I, ROBERT H. MILLER, acitizen of the United States, residin at Lansing, in the county ofIngham and tate of Michigan, have invented new and useful Improvementsin Tire-Connectors, of which the following is a specification.

This invention relates to wire connectors and the object of theinvention is to provide a simple and elicient device for connecting theterminals of electric circuit wires'and to avoid vthe use of bindingposts, nuts and screws or anyl like. devices which employ of the wires,spring actuated gripplng jaws exposed binding elements. Further objectsof the invention will appear -as the following description is read inconnection with the accompanying drawing, which forms a part of thisapplication, and in which v Figure 1 is a perspective view showing thepreferred form ofconnector. Fig. 2 is a longitudinal sectional Viewtaken therethrough and drawn on an enlarged scale.

Referring to the drawing, and mpre particularly to Figs. 1 andV 2, 1indicates a metallic sleeve 'which has secured in one end thereof acentrally apertured head 2 of conducting material, the aperture of whichis threaded to receive a binding screw of any suitable character formaking connection with a terminalof a conductor. Secured to this head isa pair of semi-cylindrical members 3 whichv have their outer endsenlarged "cna taper, asfindicated at 4, and their inner sides roughened,corrugated or toothed in ang suitable manner, as' shown at 5,l to provie a gripping surface. These' members 5 when brought together form ineffect a split clutch sleeve which is surrounded by a spiral spring 6having one end abutting the .head'2 and at its'opposite end abutting a`metallic sleeve 7 whose bore is tapered to correspondv with the taper 4of the split sleeve.

Tofthe outer end of this collar is secured an insulating button 8 whosecentral bore is of the same siz'e with the bore in the vsleeve so as topermit the passage of the insulated end lof the conductor,l the bare."termin'al of .which is engaged between the members@ .whichact in thecapacity of clampmg jaws when acted upon by theinclined inner walls ofthe sleeve 7 which coacts with the inclined ends of the membersSpecification of Letters Patent.

Application filed September 4, 1914. Serial No. 860,231.

Patented Dec. 21, 1915 3. By depressing the button theends ofthe splitsleeve will be exposed so that the bare terminal of the conductor may beinserted therein. Release of the button will cause' clamping of the jawsupon the terminal and as all parts with the exception of the button areof metal a complete connection from thebinding post or screw will be hadwith the conductor.

What is claimed is y 1. A connector for a pair of electric wirescomprising a metallic sleeve, a set screw for connecting the same to theterminalv of one of the wires, spring actuated gripping jawselectrically associated with said sleeve and adapted to grip a terminalof the remaining wire, said jaws contacting with said set screw and ahollow insulating button provided with an inclined surface for forcingsaid jaws into tight engagement with the lwire terminals.

3. A connector for a pair of electric wires comprising a sleeve, a set'screw for connecting the sleeve tothe terminal of one of said wires, apair of jaws arranged within and concentric with the sleeve, said jawscontact-ing with said set screw, a spring surrounding said jaw, a collarslidably mounted in the sleeve and adapted to operate said jaw throughthe expansive action of said spring, a head mounted within sald sleeveand secured to said jaws, and a screw threaded into said hea-d andpassing through said jaws.

4. An electric wire connector comprisingv a metallic sleeve, a headdetachably mounted in 'an end portion of said sleeve, parallel jawshaving a pair of adjacentQeXtremit-ies seated in sald head, a screwpassingthrough said head in al transverse direction and maining endportion of said sleeve and prov.through the mentioned extremities ofsaid jaws, a collar slidably mounted in the reiiciioii imi tightlybinding igiiiisi the .ex ,teinitieg A.olf sla-id Jaws vWivthvir'yl thehead. 1Q
